The lower edge of this cop is reinforced :by n bend 15 held in place by s plurality of screws 16 which extend throu h the bond and through the cop end whic project inwordly, as shown, so that they may be engaged' within the bayonet slots 13.

Mounted within oep le is o cup-sheped member 17 which hos its lower end closed and adopted to seat upon o gasket 18 disposed upon the Hangs 12 At its upper portion thecup 17 is formed with en enn larged portion dening o shoulder 19 which is engageoble with the projecting ends of the screws 16 for preventing the cup from @coming disassocioted from the cop. spring which is locoted within the oep nnd which hos one end shutting against the closed end thereof and its other end cloutting against the closed end of the cup.

ln the use of my device the cup 17 is disposed within the. cop v141- with the spring 20 in position, otter which the screws 16 ore placed in position. Assuming that thetnnk is open, in order to close it the operetor slips the cop over the neel: with the screws 16 entering the entrance ends of the looyonet.

device being so constructed and arranged that the cap may be removed and replaced in a remarkably short time and with unusual little effort.

While I have shown and described the preferred embodiment 0f my invention, it is of course to be understood that I reserve the right to make such changes in the f'orm, lconstruction and arrangement of parts as will notdepart from the spirit of the invention or the scope of the subjoined claims.

Having thus described my invention, I claim: l
